As semiconductor technology pushes toward smaller nodes, conventional planar transistors are nearing physical limits in terms of power efficiency, leakage current, and switching speed.  

Three-dimensional (3D) transistors, commonly known as FinFETs, overcome these limitations by stacking channels vertically and increasing gate control. This structure allows higher transistor density, lower power consumption, and faster switching, making them a backbone of modern CPUs and GPUs, and also high-performance computing (HPC) systems. 

The growing demand for AI, 5G, and edge computing accelerates the adoption of 3D transistors. These chips are no longer luxury enhancements; they are essential for sustaining Moore’s Law in high-performance and mobile devices.
